On the optimal consistent approximation to pairwise comparison matrices
In the process of knowledge acquisition, one important approach is to introduce weights reflecting the relative significance of the objectives concerned. In reality, however, these weights either cannot be precisely assigned or are assigned with biased judgements. Here, an important issue of retrieving consistency from data that are in disarray is discussed. A special parametrization that enables to carry out this validation process effectively has been proposed.
